1. 安装

执行命令

[root@VM-0-9-centos ~]# cd /home
[root@VM-0-9-centos home]# mkdir cmake
[root@VM-0-9-centos home]# cd cmake
[root@VM-0-9-centos cmake]# wget https://github.com/Kitware/CMake/releases/download/v3.19.0-rc3/cmake-3.19.0-rc3-Linux-x86_64.tar.gz
[root@VM-0-9-centos cmake]# tar -xvf cmake-3.19.0-rc3/
[root@VM-0-9-centos cmake]# cd cmake-3.19.0-rc3/
[root@VM-0-9-centos cmake-3.19.0-rc3]# ./bootstrap
[root@VM-0-9-centos cmake-3.19.0-rc3]# gmake
[root@VM-0-9-centos cmake-3.19.0-rc3]# gmake install

查看状态

cmake --version

2. 测试

创建测试文件夹和两个文件

[root@VM-0-9-centos cmake-3.19.0-rc3]# mkdir xltest
[root@VM-0-9-centos cmake-3.19.0-rc3]# cd xltest
[root@VM-0-9-centos xltest]# vim cmaketest.cpp
[root@VM-0-9-centos xltest]# vim CMakeLists.txt

其中cmaketest.cpp 如下

#include <iostream>
using namespace std;
int main()
{
	cout<<"Hello Cmake!"<<endl;
	return 0;
}

CMakeLists.txt 如下

cmake_minimum_required(VERSION 3.0)
project(cmaketest)
set(SOURCE cmaketest)
add_executable(${PROJECT_NAME} ${SOURCE})

执行cmake

[root@VM-0-9-centos xltest]# cmake .

执行make

[root@VM-0-9-centos xltest]# make

执行可执行文件看到如下，安装成功

[root@VM-0-9-centos xltest]# ./cmaketest
Hello Cmake!

3. 问题及解决
